Annual share of the market, in short (3)
I believe the answer is:
mar
'annual share of' is the definition.
The definition suggests a singular noun which matches the answer.
'market in short' is the wordplay.
'market' becomes 'mart' (synonyms).
'in short' means to remove the last letter.
'mart' with its last letter taken away is 'MAR'.
'the' is the link.
Can you help me to learn more?
(Other definitions for mar that I've seen before include "Spoil or deface" , "Oh dear!" , "Cause harm" , "Damage; month (abbr.)" , "Disfigure" .)
